Industrial Sodium Bicarbonate Baking Soda NaHCO3 99.0-100% Purity with 0.4% Chloride Content for Mineral Processing
Sodium bicarbonate (baking soda) is manufactured using sodium sulfate (Na₂SO₄) as raw material, sourced from sodium nitrate tailings in the sodium powder industry and by-product waste from environmental protection industries including new energy, coal chemical, metallurgical steel, and textile sectors. The production involves a double decomposition reaction with ammonium bicarbonate (NH₄HCO₃), yielding the by-product fertilizer ammonium sulfate ((NH₄)₂SO₄). The final product features low chlorine (or chlorine-free) characteristics to meet specific industry requirements for chlorine content.
